I carried out the expansion of this expression and then simplified into the relevant terms but my final answer is because the N term cancels out.
Am I starting out correctly up until this expansion or is my thought process off from the start? And if I am heading in the right direction is there any obvious reason that I may be expanding the expression incorrectly? Any help would be greatly appreciated.
